BILGE-PUMP.

Specification of Letters Patent.

Patented June 3, 1919.

Application le February 1, 1919. Serial No. 274,479.

To all whom t may concern:

Be it known that we, LEOPOLD WESTON and JOHN REID JONES, both citizens of the Dominion of New Zealand, and both residing at Rodney Road, Northcote, Auckland, in the Provincial District of Auckland, in the Dominion of New Zealand, have inven-ted certain new and useful Improvements in Improved Bilge-Pumps, of which the following is a specification.

This invention relates to pumps used for pumping bilge water from ships and boats, and provides a pump which operates by the rolling of the vessel in which the same is installed.

The invention comprises a pendulum connected to the plunger of a pump proper, the end of the pendulum being provided with a friction roller adapted to run in a race and prevent the pendulum rod from being strained during the pitching of the vessel.

The drawing herewith illustrates the invention.

Figure l, is a front elevation, and

Fig. 2, a side elevation of the pump, and

Fig. 3, is a sectional plan on line 3 3, Fig. 1.

The pendulum rod 1 and a. lateral arm 2 are fixed to a shaft 3 mounted in a standard 4., which has a base 5 fixed to a deck or the frame of the vessel. The pendulum weight or bob 6 is adjustable on the rod 1 by a nut 7 screwed upon the said rod. A friction roller 8 mounted on the end of the rod 1 is adapted to run in av curved and grooved race 9, the center of which is coincident with the center of the shaft 3. The said race is disposed transversely of the vessel, and prevents the rod 1 from being strained by the weight 6 when the vessel pitches.

The pump proper 10 is fixed to the base 5 and the plunger 11 thereof is connected by a rod 12 to the arm 2. The suction pipe 13 is led down tc the bilge of the vessel, and the delivery pipe 14E is led overboard above the surface of the water in which the vessel is floating.

When the vessel rolls, the force of gravity holds the pendulum vertically or approximately vertically, while the pump oscillates with the vessel, with the result that the cylinder of the pump 10 reciprocates on the plunger 11 and water is drawn from the bilge and forced overboard. The dotted lines in Fig. 1 shows the pump at its maximum oscillation in both directions, and the plunger l1 at its maximum reciprocation.

The stroke of the pump is adjusted by means of holes 15 provided in the arm 2, the end of the rod 12 being connected to the said arm by passing the pin 16 through any one of the said holes.

W'hat we do claim and desire to secure by Letters Patent of the United States is l. A pump adapted to oscillate with the rolling of the vessel in which the same isy fixed, a standard, a shaft journaled inthe standard, a pendulum connected tothe shaft, coactive means connected to the pendulum and adapted to be connected to the vessel for guiding the movement of lthe pendulum, a

lateral arm fixed to the shaft, and a rod connecting the arm 'to the plunger of the pump, as set forth. y

2. In a bilge pump the combination with a pendulum, of a roller operatively connected to the lower end of the penduliun and a curved and grooved race in which the friction rollerv is adapted to run. f 3. A pump adapted tooscillate with the rolling of the vessel in which the same is fixed, a standard, a shaft mounted in the standard, aV pendulum and lateral arm fixed "to the shaft, a friction roller mounted on the end of the pendulum rod, curved kand grooved race in which the friction roller Litoronn wnsrou.
